Dgraph data loss

A bit of an odd one here but an insight would save alot.
I have a couple of pvc for alpha and zero but no backup was taken via ratel.
The Kubernetes cluster no longer exist so I took a backup of the /dgraph director for both alpha and zero.
I tried to load it using a standalone image. I can see the schema exists but no useful data can be retrieved.
I had alot of very useful data that I would like to export but all I see when I try to view a sample data is some uid with no other fields populated.
Any ideas how I can retrieve a useful data?

Not sure, have you cleaned the paths before uploading yours?

Make sure the instances has the same version you used before.
